Penrhyn Slate

The Penrhyn Quarry is the oldest and largest slate quarry in the world. Although it was not commercially opened until 1784, it had been operating as a ‘cottage industry’ since at least as far back as the 13th century.

Penrhyn Slates are recognized universally as the best quality slate in the world and are sold worldwide – Ireland, the UK, mainland Europe, Australia, New Zealand and the United States are all major customers for this slate. It is the only roofing slate to have a lifespan measured in centuries.
